Keane has said that he has no intention of making the move north-of-the-border permanent when his loan at Celtic finishes at the end of the season.
"I've got a three-year contract at Tottenham so I will go back there in the summer," he said.
"It's just a loan move and always has been.
"I've got a lot of friends down at Tottenham and I miss the lads. I speak to them all the time and they are doing well at the moment.
"I also miss the tea ladies – they are very good down there!"
Keane has scored nine goals in nine games since joining Celtic on loan at the beginning of February.
